I really like this movie and this is why. It's B movie and it does not feel shame about it - just do the job and, man, it does it great.
Besides cool old guys there are pretty good effects and combat scenes. Everyone shoots from both hands, enemies die in thousandths, every couple of minutes something explodes.
But now when they've shoot second film I feel a bit sad, because in the third part they have a little choice for new old heroes to introduce in new movie. In some point this franchise probably have reached it's top point. I hope I'm wrong and Stallone with the team will shoot even better third movie, I'll certainly watch it.
